摘要 针对一类由T-S模糊模型表示的非线性时滞系统,提出一种输出反馈模糊控制器设计的新方案.首先采用PDC(并行分布补偿)的基本思想设计输出反馈控制器,然后利用T-S模糊模型扩展的稳定性条件,给出系统以稳定度α全局渐近稳定的充分条件,最后基于LMI(线性矩阵不等式)方法,将模糊控制器的设计问题转化为LMIP(线性矩阵不等式问题). A novel scheme of output feedback fuzzy control for a class of uncertain nonlinear time-delay systems represented by T-S fuzzy model is proposed. Firstly, the concept of the so-called PDC（Parallel Distributed Compensation） is employed to design the output feedback controller. Secondly, based on the relaxed stability conditions of T-S fuzzy model, sufficient conditions with respect to stability degree a are given in the sense of lyapunov asymptotic stability. Finally, by the LMI （Linear Matrix Inequality） method, the problem of designing the fuzzy controller is translated into LMIP （Linear Matrix Inequality Problem）.
